Question

x+1 ➗ by 3x²+2x¹ with solution​

Answer 1

Step-by-step explanation:

• Given polynomial p(x)=ax
• 3
• +3x
• 2
• −13 and 2x
• 2
• −5x+a is divided by x-2 get same remainder
• Then x-2=0 or x=2
• p(x)=ax
• 3
• +3x
• 2
• −13
• Replace x by 2 we get
• p(2)=a(2)
• 3
• +3(2)
• 2
• −13
• ⇒p(2)=8a+12−13
• ⇒p(2)=8a−1
• 2x
• 2
• −5x+a
• Replace x by 2 we get
• q(2)=2(2)
• 3
• −5(2)+a
• ⇒q(2)=16−10+a
• ⇒q(2)=6+a
• Given remainder is same
• ∴8a−1=6+a
• ⇒8a−1+1−a=6+a+1−a
• ⇒7a=7
• a=1
